Black Malleable Iron Hex Bushes

Hex Bushes are designed to reduce BSP thread sizes within a pipeline in a single, efficient fitting. The external hexagon profile allows for easy installation using a standard spanner, even in confined spaces, ensuring a secure and controlled tightening process.

Each fitting typically features a male BSPT thread on the outer section and a female BSPT thread internally, enabling a direct reduction between differing pipe sizes while maintaining a strong, pressure-resistant joint. When installed with appropriate sealing compounds or PTFE tape, they provide a reliable leak-tight connection suitable for demanding service conditions.

Manufactured from malleable iron, hex reducing bushes offer a combination of strength and ductility, helping them withstand mechanical stress, vibration and installation torque without cracking. This makes them well suited to both static and dynamic pipework systems.

These fittings are commonly used in fire sprinkler systems, HVAC installations, plumbing networks and industrial pipework where space efficiency and adaptability are important. Their compact design reduces the need for additional couplings or adaptors, simplifying system layouts.

Applications

Ideal for fire sprinkler systems, plumbing, heating, gas and oil pipework, HVAC installations and general mechanical services where BSP size reduction is required within a compact threaded fitting.
